BUNG FOR BARRELS, KEGS, OR CASKS.`

SPECIFICATION forming part of Letters Patent No. 682,202, datedSeptember 10, 1.901. Application led August 3, 1900. Serial No. 25,786.(No model.)

To all whom t may concern.-

Be it known that LOHARLES J. KINTNER, a citizen of the United States,residing at New York, borough of Manhattan, county of New York, andState of New York, have made a new and useful Invention in Bungs forBarrels, Kegs, or Oasks, of which the following is a specification.

My invention will be fully understood by referring to the accompanyingdrawings, in which- Figure l is a sectional View taken through the headof a barrel, a metal bung-bushing, and my improved bung, the detachablepart thereof being shown in elevation. Fig. 2 is a similar view of amodified form showing the detachable part. Fig. 3 is a plan view of theslitted rubber bung-ring shown in Fig. l, the dotted lines illustratingthe manner of re- 'moving said ring out of the bushing from the exteriorof the barrel or keg.

Referringl now to the drawings in detail, B representsl the head of abarrel, and B a welllrnown screw-threaded metal bung-bushing securedtherein, said bushing being coneshaped interiorly, as shown.

R represents a flexible or yielding non-absorbent bung-ring, madepreferably of rubber and .cone-shaped exteriorly, so as to iit snuglywithin the inner face of the interiorlycone-shaped bung-bushing B' whendriven home, s being a retaining rim or extension below or within theinner end of the bungbushing for securing it against ejection under thein lnence of the liquid and gases contained in the barrel or keg. Thisbung-ring has preferably an exterior diameter greater than the interiordiameter of the bung-bushing B, so. as"` to fit snugly therein whenforced into position, and the retaining rim or extension S is normallyof greater diameter than the interior diameter at the inner end of thebushing B for the purpose of locking the ring securely in position, sothat it cannot be withdrawn from without. This bung-ring may be slittedin the direction of its axis on one side, as shown at b, Fig. l, saidslit being preferably cut at an angle to the diameter of the bung-ring,as shown in plan view in Fig. 3. The function of this slit is for thepurpose of enabling one to remove the ring from without the barrel, aswill be described later on.

P is a detachable part cone-shaped, as shown, to fit the upper innercone-shaped surface of the ring R and provided with a rim or head s,adapted to fit behind a ledge near the upper end of the lowerinner'coneshaped surface of the bung-ring R.

C is a cord secured to the lower end of the ring R and also to thedetachable part P, its function being to prevent the detachable partfrom being wholly disconnected from the bung-ring in order that it maybe withdrawn with said ring.

The operation is as follows: Tile detachable parl P is put in place byopening the bung-ring. The two parts are then driven irmly home untilthe rim or extension s' passes beneath the inner edge of the bungbushingB', so as to lock the parts together. The detachable part P is injectedinto the barrel by the spigot in the usual way, after which thebung-ringis removed by inserting a pointed tool between one of the endsof the slitted ring and the bung-bushing B', as at t, Fig. 3, and thering caused to assume the position shown in dotted lines, when it,together with the detachable part P, which is held by the cord O, may bewithdrawn from without the barrel, after which the bung may be usedoveragain in like manner as many times as desired.

In Fig. 2 I have shown a modified form, in which the bung-ring R is notslittedl and is cone-shaped interiorly to a point near the lower orinternal end ofthe ring, the detachable part P being in the nature of aconeshaped spun or struck-up metal cup,the upper edge s of which when inposition takes behind a shoulder, as did the corresponding part s inFig. l. This detachable part P in this instance is preferably put inposition after the bung-ring R is driven home by forcing it downward bya tool to the desired point. In operation it is injected by the spigotin the usual way and washed out through the vent bung-hole during thewashing of the barrel. The bung-ring R may be removed by forcing itinward and washing or rolling it out through the vent-bung when it isdesired so to do.

. It is obvious that the plug form of the detachable part P (illustratedin Fig. l) might be substituted for the metal cup forin (illus- IOOtrated in Fig. 2) and that said part may be of any preferrednon-absorbent material and of such proportions as may suggestthemselves, so long as the rim or ledge S is so located with relation tothe ring R that when in position it is looked against ejection by thegases and liquid contained in the barrel or keg. The essential featureof my invention lies in the utilization of a coneshaped bung-ringprovided with an interior eXtension or rim,in combination with adetachable part having a similar ledge s and adapted to be locked withinthe inner surface of the ring in such manner that the gases and liquidwithin the barrel tend to iirmly hold and lock the parts together byoutward pressure.

I am aware that it has heretofore been proposed to use a ribbed orcorrugated elastic bung-ring and adetachable partin the nature of aplug, as disclosed in United States Patent No. 220,773, of October 2l,1879. Iam also aware that a cone-shaped bungring made of elasticmaterial, such as wood, has heretofore been used in connection with anespecial form of bung-bushing having an enlargement or groove at itslower inner end for receiving the outwardlypressed lower end of thebung-ring when the detachable part is forced therein, as disclosed inUnited States Patent to Reynolds et al., No. 235,653, of December 21,1880; also, that a bung has heretofore been devised with a rubberbungring seated in an especial form of bung-bushing provided withinternally projecting ledges adapted to hold the bung-ringin place, saidbung-ring having in turn an internal ledge near its upper or outer endadapted to hold a detachable part or plug in place when insertedtherein, as disclosed in United States Patent to Bokel, No. 548,625, ofOctober29, 1895, and I make no claim hereinafter broad enough to includesuch structures, my invention being particularly designed for use inconnection with the well-known form of cone-shaped metal bung-bushingsvery generally in public use, such as is indicated by the letter B inFigs. 1 and 2 of the drawings, my improvement being of such a naturethat the lower end of the bung-ring extends always a denite distancewithin or below the inner end of the bung-bushing, so as to act as ashoulder or seat adapted to prevent the ejec- Ition .of the bung by theliquid and gases contained in the barrel, and all of my claimshereinafter made distinctly embody this feature.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent of the United States, is-

1. An'eXteriorly-cone-shaped bung-ring designed for use with acorrespondingly interiorly-cone-shaped bung bushing, said ring beingprovided with a rim or extension at its inner end normally of greaterdiameter than the interior diameter of the bung-bushing and adapted,when in position in the bushing and below the lower end thereof, to holdor secure it from being withdrawn, substantially as described.

2. An eXteriorly-cone-shaped bun g-rin g designed for use with acorrespondingly interiorly-cone-shaped bungbushing, said ring beingprovided with a rim or extension at its inner end normally of greaterdiameter than the interior diameter of the bung-bushing and adapted,when in position in the busliing and below the lower end thereof, tohold or secure it from being withdrawn; in com-Y bination with adetachable part having a head or rim adapted, when in position Withinthe ring, to lock it against ejection, substantially as described,

3. An exteriorlyconeshaped bung-ring de-v signed for use with acorrespondingly inte; riorly-cone-shaped bung bushing,- said ring beingslitted on one side in the direction of its axis and provided with a rimor extension at its inner end adapted, when in position in the bushingand below the lower end thereof, to hold or secure it from beingwithdrawn,- substantially as described.

4. An exteriorly-cone-shaped bung-ring designed for use with acorrespondingly interiorly-cone-shap'ed bungbushing, said ring beingslitted on one side in the direction of its axis and provided with a rimor extension at its inner end adapted, when in position in the bushingand below the lower end thereof, to hold or secure it from beingwithdrawn; in combination with a detachable part havinga head or rimadapted, when in position within the ring, to lock it against ejection;together with a cord for preventing the detachable part from becomingseparated from the ring when said partis injected into the barrel,substantially as described.l

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.

CHARLES J. KINTNER.
